My G22 is a bare to shoot. After 30 rounds my hand is numb and I don't want anymore. I'm not a pistol guy so I just assumed this was normal until I shot a friends G27. It didn't have anywhere near the same recoil. Does this mean I need to replace the recoil spring assembly? If so, where should I get one from? I would want to make sure it was a quality part not some aftermarket crap.
